Mobile LiDAR Survey for Corridor Mapping
Vehicle, rail and boat-mounted LiDAR scanning built for highways, railways and hill roads — captured once and measured forever. Every scan becomes a permanent, survey-grade 3D record of the corridor, ready for engineering-quality CAD deliverables.
A Permanent 3D Record of the Corridor
A Mobile LiDAR pass leaves behind a lasting digital record of everything along the route — lane widths, sidewalks, building setbacks, drains, signage and pavement condition can all be measured later, straight from the point cloud, without going back to site. We process every scan to survey-grade accuracy and hand over a clean, engineering-ready 3D CAD file.
Because the system rides on a vehicle, rail bogie or boat, it moves at traffic speed while recording x, y and z coordinates continuously — turning kilometres of highway, hill road or rail corridor into a navigable 3D model far faster than a crew walking the same distance with a total station.
The productivity gap is large in practice: a 90 km highway stretch that once took roughly 120 working days to survey conventionally was captured with Mobile LiDAR in about five hours of drive time. Mobile LiDAR also holds an edge over static terrestrial scanning and most airborne systems (short of low-flying drones) when survey-grade positional accuracy matters.
Faster than Total Station/DGPS crews
Denser detail than a conventional survey
Safer — no crew standing in live traffic

Leica Pegasus: Two Mobile Mapping System
Terrain elevation matters at every stage of building, road and bridge construction, which is why our core platform pairs a calibrated LiDAR head with a 360° camera rig and a full positioning stack — GNSS receiver, IMU and a distance-measuring instrument (DMI) — so every point lands with survey-grade confidence, not just visual accuracy.
